See the platform in action.
Short walk-throughs of the platform in action, from the general overview to focused tools built for specific use cases.
Platform overview
A guided tour of the digital twin workspace, bringing BIM, GIS, and open data together in a single browser session, with the tools institutions actually use day-to-day.
Built to remove roadblocks.
No vendor lock-in
AGPL-3.0 license means you can always self-host, fork, or exit. Your investment in the platform is portable.
Data sovereignty
Sovereign managed hosting in the region of your choice, or fully on-premise self-hosting. You decide where your data lives.
Cost-recovery economics
We're a non-profit. No profit margin baked in. Any surplus is reinvested in the platform rather than extracted.
Multidisciplinary by design
Built from the start to connect BIM, GIS, research, and operations. The platform fits the way institutions actually work.
What the platform enables.
Bridge BIM, GIS, and open data
Visualize and analyze multi-scale digital twins in a single browser-based workspace, from individual buildings to regional landscapes.
Interoperable by design
Open standards and open formats. Connect existing pipelines and tools without proprietary gatekeepers.
Extend and integrate
Build analysis tools, custom extensions, and integrations through documented APIs.
Deploy your way
Use the managed sovereign service or self-host the AGPL-3.0 core on your infrastructure. Switch between modes without re-platforming.
Customize without forking
Commission specialized features on a cost-recovery basis, built on the open core so you stay on the upgrade path.
Equip your team
Formal training and capacity-building programs for institutions adopting digital twin practice.

Frequently asked questions
Straight answers on where your data lives, who can reach it, is it secure and private, and how an open platform keeps you in control.
With CDT Hosted, the platform runs on sovereign infrastructure, managed for you in Canada or installed by our team on infrastructure you choose, so your data stays within the jurisdiction you require. If you self-host the containerized stack, your data never leaves your own infrastructure.
Compare deployment & hosting optionsOnly the people you authorize. Access is governed by role-based permissions on a least-privilege model, and every sign-in is protected by multi-factor authentication. With self-managed deployments, no one outside your organization has access, and we never sell or share your data.
Read about roles & permissionsYes. The core is published under the AGPL-3.0 licence, so you can read, audit, self-host, and modify the source. There is no proprietary black box. A separate commercial licence is available for organizations that need different terms, and any revenue funds the non-profit's mission.
Browse the source on GitHubThe platform is built on open standards (IFC, GeoJSON, LAS, BCF, and IDS), so you can export your data in bulk and self-host the open-source core at any time. You can even add new tools and viewers through the plugin system without forking the codebase. Your investment stays portable.
See the open standards we useAbsolutely. CDT ships as a containerized stack that starts with a single command via Docker or Podman, entirely on-premises or in your own cloud, giving you complete control over data, network, and integrations.
